Description

The present invention relates to a surface material opener and fittings.

Some fixtures, such as sliding doors, that have a panel that is movably arranged along the horizontal frame of the frame are equipped with a panel opener. Fittings such as sliding doors generally have a handle on the surface of the panel that is the leading edge of the panel, and the panel can be opened by operating the handle. Panel openers are designed to open the panel without touching the handle. An example of this type of panel opener is described in Patent Document 1. In this panel opener, a pressing member and a link mechanism are provided on the vertical frame, and when the link mechanism is operated via the operation input unit, the pressing member presses the end surface of the panel that is the leading edge of the panel, making it possible to open the panel.

JP 2020-84404 A

In the above-mentioned panel opener, in order to close the panel without leaving a gap between the panel and the vertical frame, the pressing member and part of the link mechanism that operates it must be housed inside the vertical frame. For this reason, when retrofitting an existing fixture, complicated work is unavoidable. One solution to this problem is to add a new vertical frame with a built-in panel opener to the existing vertical frame. However, when a new vertical frame is added to a fixture, not only does the opening area decrease when the panel is opened, but work is required to match the dimensions of the new vertical frame to the dimensions between the upper and lower frames.

In view of the above-mentioned circumstances, the present invention aims to provide a panel opener and fitting that can be easily installed without reducing the opening area of the fitting.

In order to achieve the above object, the panel opener of the present invention is a panel opener for fittings, comprising a frame body having horizontal and vertical frames, and a panel arranged to be movable along the extension direction of the horizontal frame, and is characterized in that it comprises a receiving member provided on the panel in a state protruding from at least one surface of the panel, a pressing member arranged in a position facing the receiving member, and a link mechanism extending vertically along the vertical frame, with an upper end connected to the pressing member and a lower end connected to an operation input unit, which moves downward relative to the vertical frame when the operation input unit is operated, thereby pressing the receiving member via the pressing member.

According to the present invention, a receiving member is provided on the surface of the panel, and the pressing member is configured to press the receiving member, so it is possible to ensure airtightness between the projected surface of the panel and the projected surface of the vertical frame without having to house the pressing member inside the vertical frame. Moreover, the pressing member and link mechanism do not need to be provided with no gaps between the upper and lower frames. As a result, no complicated work is required when retrofitting to existing fixtures, and it is possible to prevent a situation in which the opening area is significantly reduced when the panel is opened.

The following describes in detail preferred embodiments of the surface material opener and fittings according to the present invention with reference to the attached drawings. For convenience, the terms "prospect direction" and "finding direction" may be used below. The "prospect direction" is the direction along the depth of the fittings, as shown by arrow A in the figure. A surface along the prospect direction may be referred to as a "prospect surface." The "finding direction" is the direction along the top and bottom perpendicular to the prospect direction in the case of an object that extends horizontally, such as an upper frame. In the case of an object that extends vertically, such as a vertical frame, the direction along the horizontal perpendicular to the prospect direction is called the "finding direction." A surface along the prospect direction may be called a "finding surface."

Figures 1 to 3 show a surface material opener according to an embodiment of the present invention. The surface material opener 1 illustrated here is applied to a fitting known as a single-sided sliding door, which is installed in an opening in a wall body W that separates a corridor from a room indoors, as shown in Figures 4 to 7. Below, we will explain the sliding door to which the surface material opener is applied. A single-sided sliding door is composed of a frame body 10 and a door body (surface material) 20.

The frame body 10 is configured in a rectangular shape with an upper frame (horizontal frame) 11, a lower frame (horizontal frame) 12, and left and right vertical frames 13, 14, and further configured by providing uprights 15 along the top and bottom of the part on the room side between the upper frame 11 and the lower frame 12. The vertical frame located on the left side as seen from the aisle side (hereinafter referred to as the end frame 13 when distinguishing between them) is configured to have a larger dimension along the projection direction than the vertical frame located on the right side as seen from the aisle side (hereinafter referred to as the tail frame 14 when distinguishing between them) and the upright 15. The projection surface 13a of the end frame 13 faces the projection surface 14a of the tail frame 14 and the projection surface 15a of the upright 15, and is approximately parallel to the projection surface 14a of the tail frame 14 and the projection surface 15a of the upright 15. The front surface 13b located on the passage side of the front frame 13 is located on approximately the same plane as the front surface 14b of the tail frame 14 and the front surface 12b of the bottom frame 12. The front surface 13c located on the room side of the front frame 13 is located on approximately the same plane as the front surface 15c of the upright 15 and the front surface 12c of the bottom frame 12. An opening that is opened and closed by the door body 20 is formed between the front frame 13 and the upright 15. The space between the tail frame 14 and the upright 15 is closed by a sleeve wall W1. The part located on the passage side between the upright 15 and the tail frame 14 becomes a door pocket that accommodates the door body 20 when the opening is opened. The front surface 13a of the front frame 13 and the front surface 14a of the tail frame 14 have recesses 13d, 14d in the parts facing each other. The recesses 13d and 14d are configured so that their width along the front direction is greater than the thickness of the door body 20, and are provided along the entire length of the door end frame 13 and the door end frame 14. The reference symbol in the figure indicates the mohair 15e provided on the visible surface of the mullion 15 that faces the door body 20.

The door body 20 is a flat member formed to a size that can close the opening between the door end frame 13 and the upright 15. Although not shown in the figure, the door body 20 is supported on the upper frame 11 via a hanging mechanism provided at the upper end, for example, so that it can move along the extension direction of the upper frame 11 in the area where the recess 13d of the door end frame 13 and the recess 14d of the door end frame 14 face each other. The plate thickness of the door body 20 is set to be smaller than the dimension along the projection direction of the door end frame 14. In the example shown in the figure, the plate thickness of the door body 20 is set to be 1/2 or less of the dimension along the projection direction of the door end frame 14. Furthermore, as is clear from the figure, the door body 20 is arranged in a position close to the upright 15 in the projection direction of the frame body 10. As a result, a space is secured in the portion of the frame 10 that is closer to the aisle than the door body 20, and the dimension along the projection direction is approximately half the dimension along the projection direction of the tail frame 14. The door body 20 has handles 21 attached to both sides of the door end side, approximately in the center in the height direction.

The above-mentioned panel opener 1 is for opening the door body 20 without touching the handle 21 when entering a room from the aisle side, and as shown in Figures 1 to 3, it is equipped with a receiving member 31, a link bar (link mechanism) 32, a push pedal (operation input unit) 33, and a push arm (pushing member) 34.

The receiving member 31 is attached to the passage-side surface (one surface) 20a of the door body 20 below the handle 21, and has a receiving body 31a and a cover 31b. The receiving body 31a is a vertically long rectangular parallelepiped, and the receiving surface 31c facing the door end frame 13 is fixed to the door end side of the door body 20 in a state where it is almost vertical along the projection direction. As is clear from the figure, the receiving surface 31c of the receiving body 31a is located on the door tail side of the projection surface 20c (hereinafter simply referred to as the door end surface) located on the door end side of the door body 20. The protruding end surface 31d of the receiving body 31a toward the passage side is set so as not to protrude from the visible surface 13b located on the passage side of the door end frame 13. The cover portion 31b is a thin plate that protrudes from the protruding end of the receiving body portion 31a toward the visible surface 13a of the door frame 13, and extends so as to secure a gap between it and the aisle side surface 20a of the door body 20 and to be approximately parallel to the aisle side surface 20a of the door body 20. The extension length of the cover portion 31b is set so that the extended edge does not come into contact with the visible surface 13a of the door frame 13 even when the door body 20 is closed.

The link bar 32 is a long, flat plate-like member having an arm connection part 32a at its upper end and an operation linkage part 32b at its lower end. The arm connection part 32a is rotatably connected to the upper end of the pressing arm 34 (described later) via a linkage shaft 32c extending along the projection direction. The operation linkage part 32b is connected to the operation part 33a of the pressing pedal 33 (described later) via a connecting screw (not shown). The link bar 32 has a slide guide hole 32d in the middle. The slide guide hole 32d is a slit-shaped hole extending along the length of the link bar 32 at a part that is approximately the center of the width of the link bar 32. The link bar 32 is attached to the projection surface 13a of the door frame 13 in a vertical direction by screwing the mounting screw S into the door frame 13 through the screw insertion hole 35a of the guide member 35 and the slide guide hole 32d. The position where the link bar 32 is attached is on the aisle side of the recess 13d on the front surface 13a of the door frame 13, and on the room side of the cover part 31b of the receiving member 31. That is, in this fitting, the link bar 32 is arranged to be movable vertically within the front range facing the receiving surface 31c of the receiving member 31 on the front surface 13a of the door frame 13. The guide member 35 has a cross-sectional shape that can cover the surface and both sides of the link bar 32, and forms a guide groove between the front surface 13a of the door frame 13 and the link bar 32 that can move only vertically, and is set to a longitudinal dimension shorter than that of the link bar 32. The guide member 35 has an arm support part 35b at the lower part. The arm support part 35b rotatably supports the lower end of the pressing arm 34 described later via a support shaft 35c extending along the front direction.

The push pedal 33 has an operating part 33a supported on a base 33b so as to be movable in the vertical direction. The operating part 33a is a substantially rectangular parallelepiped with a flat operating surface 33c at its upper end. The height and area of the operating surface 33c of the operating part 33a are set so that it can be easily pressed down with a foot even when it is positioned at the top. A spring (biasing member) 33d that constantly biases the operating part 33a upward is built in between the base 33b and the operating part 33a. The biasing force of the spring 33d is set so that the operating part 33a can be maintained upward with respect to the base 33b even when the link bar 32 is connected to the operating part 33a and the pressing arm 34 is connected to the link bar 32. This push pedal 33 is attached to the lower end of the door frame 13 via the mounting bracket 33e by fixing the base 33b to the mounting bracket 33e attached to the front surface 13a of the door frame 13. As is clear from the figure, the dimensions of the mounting bracket 33e, base 33b, and operating part 33a along the front direction are all set so that they can be placed in the space secured on the aisle side of the door body 20 in the frame body 10.

The pressing arm 34 is configured with two arm members 34b whose ends are rotatably connected by a connecting shaft 34a. A pressing roller 34c is arranged at the connecting portion of the two arm members 34b. The pressing roller 34c is cylindrical with the connecting shaft 34a at its center and can rotate relative to the axis of the connecting shaft 34a. The outer diameter of the pressing roller 34c is set so that the outer peripheral surface is always in a state of protruding outward from the non-operating position where the two arm members 34b are arranged in a straight line to the operating position where the two arm members 34b are arranged in a bent state. However, the outer diameter dimension of the pressing roller 34c is set to be smaller than the gap secured between the receiving surface 31c of the receiving member 31 and the projection surface 13a of the door frame 13 even when the door body 20 is closed. The upper end of the pressing arm 34 is connected to the arm connection part 32a of the link bar 32 via the link shaft 32c, and the lower end is connected to the arm support part 35b of the guide member 35 via the support shaft 35c. The dimensions of the pressing arm 34, the arm support part 35b of the guide member 35, and the link bar 32 are set so that when the operating part 33a of the pressing pedal 33 is positioned at the uppermost position due to the biasing force of the spring 33d, the pressing arm 34 is positioned in the inoperative position and the pressing roller faces the receiving surface 31c of the receiving member 31.

In the fitting having the surface material opener 1 configured as described above, when no external force is applied to the operating part 33a, as shown in Figures 4(a), 5(a), 6(a), and 7(a), the link bar 32 is positioned upward, and the pressing arm 34 is in the inoperative position. Therefore, even when the door body 20 is moved in the closing direction, the pressing arm 34 and the receiving member 31 do not come into contact with each other, and the door body 20 can be placed in the closed position. The closed position of the door body 20 is a state in which the door end surface 20c of the door body 20 is accommodated in the recess 13d beyond the projection surface 13a of the door end frame 13, and no linear gap is generated between the door body 20 and the door end frame 13 along the projection direction. When the door body 20 is placed in the closed position, ventilation between the passage and the room is suppressed by cooperation with the mohair 15e of the mullion 15, and the passage and the room can be separated while ensuring the desired airtightness. In this closed position, the door end surface 20c of the door body 20 does not necessarily have to abut against the door end frame 13 at the recess 13d.

When the operation surface 33c of the operation unit 33a is pressed down with the foot from a state in which the door body 20 is in the closed position, the upper end of the pressing arm 34 moves downward via the link bar 32, as shown in Figures 4(b), 5(b), 6(b), and 7(b). As a result, the pressing arm 34 is bent and placed in the operating position, and the pressing roller 34c facing the receiving member 31 moves in a direction away from the door end frame 13, so that the door body 20 is pressed in the opening direction via the receiving surface 31c of the receiving member 31. In other words, with this fixture, it is possible to move the door body 20 placed in the closed position to the open position without touching the handle 21 provided on the door body 20. Therefore, for example, if the pressing roller 34c is set to protrude about 100 mm from the projection surface 13a of the door end frame 13 when the link bar 32 is placed in the lowest position, it is also possible to open the door body 20 to the fully open position by inserting your body into the gap generated between the door end frame 13 and the door body 20. This eliminates the risk of hygiene problems even if the door is installed in a room where many people enter and exit. In addition, the door 20 can be opened even when both hands are occupied with luggage, etc., which is extremely advantageous in terms of usability. When the foot is removed from the operating part 33a, the operating part 33a moves upward due to the biasing force of the spring 33d regardless of whether the door 20 is open or closed, and the link bar 32 moves upward accordingly, so the pressing arm 34 returns to its inoperative state. Therefore, the pressing arm 34 that protrudes when the door 20 is opened does not get in the way when entering or exiting, and does not lead to a situation in which the opening area of the door 20 is significantly reduced when the door 20 is opened.

In addition, all of the components of the above-mentioned surface material opener 1 remain exposed to the outside of the frame body 10. Therefore, even when retrofitting to existing fixtures, no complicated work is required, and maintenance work can be easily performed. On the other hand, since all of the components, including the push pedal 33, are housed within the projected surface of the frame body 10, they do not interfere with pedestrians passing through the passage along the passage-side surface 20a of the door body 20. Furthermore, the closed position of the door body 20 relative to the frame body 10 does not change before and after the installation of the surface material opener 1, and it is possible to maintain the airtightness originally ensured between the passage and the room, even after the installation of the surface material opener 1.

Furthermore, when the link bar 32 moves upward and the pressing arm 34 presses the receiving member 31, the rigidity of the link bar 32 must be considered so that it does not buckle, and the plate thickness must be large. In contrast, in the above-mentioned surface material opener 1, the pressing pedal 33 is provided at the lower end of the link bar 32, and when the link bar 32 moves downward, the receiving member 31 is pressed via the pressing arm 34. In other words, a tensile force acts on the link bar 32 when the receiving member 31 is pressed. Therefore, there is no need to consider buckling for the link bar 32, and not only can it be made thinner, but a flexible cord-like body such as a wire can be used, and a larger opening area can be secured when the surface material is opened. When a wire is used as the link mechanism, the spring 33d of the pressing pedal 33 can be omitted, and a biasing means can be built into the link mechanism.

In the above-mentioned embodiment, the door is provided on a wall that separates a passageway from a room indoors, but the present invention is not limited to this. For example, the door may be provided on a wall that separates rooms indoors, or on a wall that separates the indoors from the outdoors. In this case, the surface material does not necessarily have to be a door body, and may be a glass plate with a frame around all four sides. Also, the door is not limited to a single surface material on a frame body, and may be a window with multiple surface materials, such as a sliding window. Furthermore, the surface material does not necessarily have to be supported on the upper frame via a hanging mechanism, and may be supported so as to be openable and closable via a wheel provided at the lower end.

In addition, in the above-described embodiment, a recess is formed on the visible surface of the door end frame, and the door end portion of the door body is accommodated in the recess when the door body is placed in the closed position, but it is not necessary to provide a recess in the door end frame, and the door body may be configured so that its door end surface abuts against the visible surface of the door end frame when it is placed in the closed position.

In addition, in the above-mentioned embodiment, the receiving member is disposed only on one surface of the panel, but a receiving member may also be disposed on the other surface, and a pressing member and a link mechanism may be provided to press the receiving member on the other surface. The receiving member does not need to be configured as a separate member from the handle, and the handle may also be used as the receiving member. In addition, the protruding end face of the receiving member is positioned on approximately the same plane as the visible surface located on the aisle side of the vertical frame, but the present invention is not limited to this. Furthermore, the pressing member is exemplified as being configured to press the receiving member when the two arm members are bent, but the present invention is not limited to this. In addition, the pressing member is not necessarily limited to being equipped with a pressing roller.

Furthermore, in the above-mentioned embodiment, the push pedal is attached to the visible surface of the vertical frame via a mounting bracket, so it can be applied to building materials without being limited by the material of the flooring, but it is not necessary to attach the push pedal to the vertical frame.

As described above, the panel opener of the present invention is a panel opener for building materials comprising a frame body having horizontal and vertical frames, and a panel arranged so as to be movable along the extension direction of the horizontal frame, and is characterized in that it comprises a receiving member provided on the panel so as to protrude from at least one surface of the panel, a pressing member arranged in a position opposite the receiving member, and a link mechanism extending vertically along the vertical frame, having an upper end connected to the pressing member and a lower end connected to an operation input unit, and which moves downward relative to the vertical frame when the operation input unit is operated, thereby pressing the receiving member via the pressing member.
According to this invention, since the receiving member is provided on the surface of the panel and the pressing member is configured to press the receiving member, it is possible to ensure airtightness between the projected surface of the panel and the projected surface of the vertical frame without having to accommodate the pressing member inside the vertical frame. Moreover, the pressing member and the link mechanism do not need to be provided without a gap between the upper frame and the lower frame. As a result, even when retrofitting to an existing door and window, complicated work is not required, and it is possible to prevent a situation in which the opening area is significantly reduced when the panel is opened. Moreover, an operation input unit is provided at the lower end of the link mechanism, and the receiving member is pressed via the pressing member when the link mechanism moves downward. In other words, a tensile force is applied to the link mechanism when the receiving member is pressed. As a result, it is not necessary to consider buckling for the link mechanism, and not only can it be made thinner, but also a flexible cord-like body such as a wire can be applied, making it possible to ensure a larger opening area when the panel is opened.

Furthermore, the present invention is characterized in that, in the above-mentioned surface material opener, the operation input unit is arranged to be movable in the vertical direction relative to the base, and is equipped with an operation unit having an operation surface on its upper surface, and when an operating force is applied to the operation surface, it moves downward relative to the base, thereby moving the link mechanism downward.
According to this invention, the operating unit can have an operating surface large enough to be stepped on, and can be housed within the visible surface area of the frame, thereby enabling space saving.

The present invention is also characterized in that, in the above-mentioned surface material opener, the operation input unit has a biasing member between the base and the operation unit which constantly biases the operation unit upward relative to the base.
According to this invention, there is no need to provide a biasing member in the link mechanism, and the link mechanism can be made even thinner.

The present invention is also characterized in that, in the above-mentioned surface material opener, the operation input unit is provided with a mounting bracket that is attached to the visible surface of the vertical frame, and the base is attached to the mounting bracket.
According to this invention, since there is no need to attach the operation input unit to the floor surface, it can be applied to building materials without being limited by the material of the flooring.

The fitting according to the present invention is characterized in that it is provided with the above-mentioned panel opener.
According to this invention, since the receiving member is provided on the surface of the panel and the pressing member is configured to press the receiving member, it is possible to ensure airtightness between the projected surface of the panel and the projected surface of the vertical frame without having to accommodate the pressing member inside the vertical frame. Moreover, the pressing member and the link mechanism do not need to be provided without a gap between the upper frame and the lower frame. As a result, even when retrofitting to an existing door and window, complicated work is not required, and it is possible to prevent a situation in which the opening area is significantly reduced when the panel is opened. Moreover, an operation input unit is provided at the lower end of the link mechanism, and the receiving member is pressed via the pressing member when the link mechanism moves downward. In other words, a tensile force is applied to the link mechanism when the receiving member is pressed. As a result, it is not necessary to consider buckling for the link mechanism, and not only can it be made thinner, but also a flexible cord-like body such as a wire can be applied, making it possible to ensure a larger opening area when the panel is opened.

The present invention is also characterized in that, in the above-mentioned building fixture, the pressing member and the link mechanism are provided on the visible surface of the vertical frame.
